 A more comprehensive test of what fields are present [and optionally
 initialized] in a stuct S.  fs is either a single field name or a cell
 array of field names.  The presence of all fields in fs are tested for in
 S, tf is true iif all fs are present. Additionally, if isinit==1, then tf
 is true iff every field fs of every element of S is nonempty (test done
 using isempty).

 USAGE
  tf = isfield2( S, fs, [isinit] )

 INPUTS
  S        - struct array
  fs       - cell of string name or string
  isinit   - [0] if true additionally test if all fields are initialized

 OUTPUTS
  tf      - true or false, depending on results of above tests

 EXAMPLE
  isfield2( struct('a',1,'b',2), {'a','b'}, 1 )
